Compact Optically Pumped High Power Midwave IR Lasers.

摘要

We have proposed a novel packaging scheme for high-power optically pumped mid-wave infrared lasers. The proposed device module does not require optics for alignment and is very compact in size. The module is made from copper and allows the pump laser to be moved relative to the mid-wave infrared laser by adjusting set-screws. Room temperature Fourier transform infrared spectroscopy measurements have been performed to measure the electroluminescence spectrum of the optically pumped mid-wave infrared laser which emits at 3.08 micrometers at room temperature. The best results were obtained at 77 K where we observe weak electroluminescence at approximately 2.7 micrometers. The optical pumping wavelength is 0.809 micrometers with a current of 10 A and 6 W of optical power.
